AUTOMATIC TRIP FOR GRAIN-BINDERS.

SPECIFICATION forming part of Letters Patent No. 380.605, dated April 3, 1888.

Applicnticn filed May 3, 1884. SeriulNo. 130.199.

To aZZ whom, it may concern.-

Be it known that I, OLE O. SToRLE, ofiMilwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Automatic Trips for Grain-Binders; and I do hereby declare that the following'is a full, clear, and exact description thereof.

My invention relates to that class of grainbinding machines in which the binding mechanism is driven intermittingly from a constantly-rotating wheel through the medium of a clutch which is tripped into action through intermediate devices by a compressor arm which yields under the pressure of the gavel.

While the invention is applicable to niachines of various forms, it is designed more particularly for machines of the so called Appleby type, and it is in this application that it is illustrated in the accompanying drawings.

As the grain delivering or packing mechanism and the mechanism for applying and fastening the band may be of ordinary construction and are foreign to my invention, it is deemed unnecessary to illustrate them in the drawings, which show only those partsimmediately associated with my improvement.

Figure 1 represents an end elevation of a portion of a binder having my improvements embodied therein, with the parts in the normal position occupied during the formation of the gavel. Fig. 2 is a similar view with the binder-operating gear-wheel removed and the driving-clutch shown in section. Fig. 3 is an elevation of the clutch and trip mechanism in the position they occupy near the completion of the binding operation. Fig. 4. is aside elevation of the parts shownin Fig. 1. Fig. 5 is an end elevation of the machine in the act of discharging the bundle. Fig. 6 is atransverse section through the driving-clutch and the adjacent parts on the line a; a: of Figs. 1, 8, and

5. Fig. 7 is a transverse section through the upper end of the compressor-operating pitman and the attendant parts. Fig. Sis an elevation, partly in section, showing the driving and tripping devices in the positions occupied immediately after the tripping action.

Referring to the drawings, A represents the main binder-framepf the usual Appleby type,

(No model.)

having an upright standard, a horizontal tubular top arm, A, supporting the knotterdriving shaft B, and a horizontal lower arm, A

containing the rock-shaft H, which carries the I bindingneedle, commonlyknown as the needleshaft.

The knotter-driving shaftBhas fixed on one end, as usual, the large binder-operating gearwheel 0, containing a cam, c, to actuate the compressor. The needle-shaft Hhas at one end a rigid crank, H, connected by a pitman,

I, to a wrist-pin, c, on the main gearwheel, so that at each revolution of the wheel the needle is thrown upward and downward in the ordi- 6 5' nary manner. The main gear receives an intermitting motion through a pinion, D, mounted loosely on a stud, E, projecting from an ear, E, on the binder-frame. The pinion D is provided, as in Fig. 6, with a tubular 7o hub, D, which gives support to a constantlyrevolving sprocket-wheel, F, mounted thereon, this wheel receiving motion through a chain, F The driving-wheel F is formed on the side next to the pinion D with a peripheral rim or flange having internal teeth or shoulders, f.

To the pinion D at G is pivoted an angular clutch-dog, G, having at its inner end a lateral roller or projection, 51', projecting within the side of the driving-wheel F. A spring, 9 seated within and carried by the pinion D, bears at one end against the clutch-dog and tends to force its inner end outward into engagement with the shoulders f of the driving- 8 5 wheel. When the parts are thus engaged, motion is communicated from the wheel F through the dog G to pinion D and thence to the binder-gear. To hold this clutch-dog nor mally out of action and permit its engagement 0 only when the gavel has acquired the proper size for binding, I make use of theparts which I will now describe.

To the end of the rock-shaft J which carries the trip and compressor J isfixcdacrank, 5 J, connected by a pitman, K, to an arm, L, which latter is pivoted to the binder-frame at Z and actuated through a stud or roller, 1, on its side by a cam, c, of the binder-gear G, the general arrangement being similar to that in I00 the existing machines.

The compressor-operating pitman K is provided near its upper end with alateral stud or shoulder, K, to control the clutch tripping device, hereinafter described. To the main binder-gear G, or to the end of its shaft, I secure in such manner as to revolve therewith the clutch-tripping arm Q,of T form, one end of which is widened, as shown at q, and arranged in such position that when the compressor is in its elevated position this end will abut against and be arrested by the stud K on the compressor-operating pitman. The opposite end, q, of the trip-arm is shaped and arranged in such position that when the arm is arrested by the stud K the end q will stand in the path of the clutch-dog G, so that as the dog revolves with the pinion D it will encounter the end q and be thrown thereby into the position shown in Fig. 2, so as to disengage the driving-wheel F and permit the pinion to stop while the driver continues its motion. When the compressor-pitman is moved so as to carry its stud K out of engagement with the trip Q, the latter will yield and permit the clutch-dog G to re-engage the driving-wheel F and again set the binder in motion. In order to permit thcvmovement ofthe pitman for this purpose and to give an elastic support to the compressor, I unite the upper end of the compressor-pitman K with the controllinglever L by a spring-connection such as shown more particularly in Fig. 7. The upper end of the pitman is reduced in size and fashioned into a tenon, k having a shoulder, k at its lower end. On this tenon I mount the arms of a C-shaped frame, M, the lower end of which bears upon the shoulder k. The controlling-lever L is attached at its outer end to a journal or pivot, m, on the frame M.

Within the frame M and upon its lower arm I seat the compressor-spring N. On top of this spring around the tenon I mount a plate, 0, having a tubular or cup-like neck, 0, which extends upward loosely through the top of the frame M. In this plate I seat the trip-spring I, the upper end of which bears beneath an adjustable nut, k screwed on the upper end of the pitman tenon. This trip spring is weaker than the compressor-spring. As the lever L under the influence of the cam urges the frame M upward in the act of compressing the grain, the nut k encounters the end of the plate or housing 0, so that the strength of the spring N is brought to bear in effecting the compression. Beneath the trip-spring Pthere is inserted a series of removable washers, p, by which the tension of the trip-spring may be varied as desired. The advantage of adjusting the trip-spring by these washers instead of by the nut 10* lies in the fact that it always affords sufficient space between the nut 7c and the top of the plate 0 to admit of the pitman K descending sufficiently to release the trip Q. If the nut is were turned down, it might happen that the pitman would have an insufficient movement to release the trip.

In place of the washers other suitable devices may be employed beneath the trip-spring p to regulate its tension.

7 The action of the parts is as follows: The compressor,its actuating-arm L, and the springconnection stand normally as shown in Flgs. 1, 2, and 7, the stud K being in contact wlth the trip Q, which keeps the driving-clutch out of action. When the gavel acquires the predetermined size, its pressure against thearm J 2 causes the pitman K to be drawn downward,

overcoming the resistance of the trip-spring 1?. As the pitman descends its stud K is car-.

ried below the end q of the trip Q, which, be-

ing released, yields and swings over the stud, as in Fig. 8. v This permits the spring g to throw the outer end of the clutch-dog G past the end of the trip, so that the clutch is immediately brought into action and the binder set in motion. The outer end of the clutch-dog G is widened, as shown at g, so-that although the dog is carried with the pinion in its rota-, tion it remains in contact with the trip, as in Fig. 8, and holds the latter out of action until the pitman has been lowered by the lever L, so that there is no danger of the stud K re-engaging the trip. The parts now continue their movement, assuming successively the position shown in Fig, 5, so that the compressor is de pressed to discharge the bundle, the position shown in Fig. 3, in which the trip Q, having nearly completed its revolution, is again in the path of the trip G, and finally the original position shown in Figs. 1 and 2, in which the dog has encounteredand been thrown out of action by the trip Q, which has in its turn been arrested by the stud K.

In order to render the action of the parts easy and certain, the trip arm Q may be fitted looselyto the carrying wheel or shaft, as indicated by dotted lines a in Fig. 8, in such manner as to have a slight freedom of movement thereon in the direction of its rotation, so that it will readily yield and move forward under the pressure of the dog G when released by the stud K.

When the parts are constructed as shown in the drawings, this independent motion of the arm Q is not necessary, as the pressure of the grain exerted through the needle-arm and the compressor and the intermediate connections to the wheel 0 will tend to turn the wheel slightly forward, so that the arm Q may ad- Vance from under the dog G as soon as the stud K moves away from its opposite end.

In a grain-binder, the rotary clutch-tripping arm driven by the knotter-drivingfshaft, in combination with a lug or stop on the compressor-operating pitman, and a clutch-dog pivoted to the pinion, which actuates the binder-operating gear-wheel, substantially as set forth.
